Replace the fuse for the cigarette lighter on a 2004 Pontiac Montana?

To replace the fuse for the cigarette lighter on a 2004 Pontiac Montana, first locate the fuse box, which is typically found under the dashboard on the driver's side. Use the fuse diagram on the cover or in the owner's manual to identify the specific fuse for the cigarette lighter, usually designated as "CIG" or similar. Remove the blown fuse using a fuse puller or pliers, then insert a new fuse of the same amperage. Finally, test the cigarette lighter to ensure it is functioning properly.
